Optimal Incomplete Block Designs
通过E准则（最小化最大方差）寻找最优不完全区组设计，开发了基于图的设计选择方法，并提供了多达15个处理水平的E最优区组设计近乎完整的解决方案。
Optimal incomplete block designs are pursued through the E criterion of minimizing maximal variance. Methodology is developed for design choice based on graphs and an extensive catalog of downloadable designs is compiled. Along with the general methodology, a near complete solution for E-optimal block designs is provided for up to 15 treatments. E optimality is revealed to be a flexible criterion that, depending on the application, can offer many choices for good designs.
